I'm new to the RV world and just bought a new 2015 ST33FR. There is a floor panel inside with four valves. I have no idea which position these valves should be in and which valve is for what. can anyone tell me what each valve is for and what position they should be in for normal operation? I know the RV dealer said something about if they weren't right I could have water shooting out the top of the RV. Scared me and he went through it so fast I didn't catch everything. Is there a DVD out there that would help me on all these valves and connections I could purchase for this model?

I am going to guess it is the water heater by pass (3 valves) and a winterizing tank bypass (1 valve w/about a 2-3 ft hose with open end to stick into non-tox antifreeze jug) The 3 valves need to all be pointing in the same direction..ie:all vertical for regular use or all horizontal for bypassing the water heater.
As for water shooting out the top, the salesman needs some training..

It may, I called the RV dealer and they explained a little more. They really should have a place to obtain a DVD for the model you have so you can learn everything about the RV. I have a couple of more questions, I'm looking for the drain for the fresh water tank. I know how to drain the gray and black tanks. While looking for the fresh water tank drain I found three hoses underneath, two blue and one red with screw of black caps. I'm assuming one is to drain the lines (blue) and one is for the hot water tank (red) to drain. They are all located next to each other. I'll also attach a photo of the valves we were speaking about. The picture is me standing over the top of the compartment looking down into it.
